博士 === 國立臺灣大學 === 土木工程學研究所 === 103 === With the progression of urbanization, the increases of impervious cover and regional sewerage system changed the runoff patterns and aggravated the floods problems in urban area. In recent years, the Construction and Planning Agency, Ministry of the Interior is propelling the strategies of urban planning and enact laws to enhance the capacity of surface infiltration and urban hazard-resilient. Effective strategy plannings are, therefore, relies on quantitative and qualitative studies that integrates hydraulic engineering and urban planning approaches to investigate the effects of these two approaches on reducing urban runoff. The main purpose of this study is the use of physical models, the use of water Low Impact Development of facilities of the retaining capacity, Quantify the effectiveness of low-impact development policy. Prevention concept to provide water to the city within the city to implement the management plan, and the related principles are urban design review. The results show, Modified Permeable Pavers (22%-45%) water retaining capacity is better than the traditional Permeable Pavers (7-9%); Rain Garden : transverse plants (10% to 37%) is better than single plant (6.8%-17.3%); Grassed Swales 0.5°>1°>3°; Green Roofs 0°>10°>30°. Accordingly the rate of subsequent numerical model results provide experimental verification of the set, and with reference to the follow-up project planning and design.
